Spatial SQL: A Practical Approach to Modern GIS Using SQL
by Matthew Forrest
Learn to create, index and query spatial databases using SQL that applies to PostgreSQL/PostGIS and more.
Learn how to use Spatial SQL to analyze and manipulate geographic data. This book covers everything from basic spatial queries to advanced spatial analysis techniques all using SQL. Even if you don't know how SQL, this book starts from the beginning all the way to advanced queries.
Over 500 pages covers a comprehensive set of GIS topics.
